SPECIFICATION forming part of Letters Patent No. 280,674, dated July 3, 1883,

Applieation filed September 29, 1882. (No model.)

To all whom, it may concern.-

Be it known that I, FRANK SOHREIDT, a citizen of the United States, residing at Mansfield, in the county of Richland, State of Ohio, have invented certain new and useful Improvements in Vehicle Shifting-Rails, of which the following is a specification.

The object of my invention is a convenient means for coupling together the rail, seatirons, and back-supports of a buggy-seat, and also to provide seat-irons which are adapted to nearly all the seats now made. These ends are attained by the means illustrated in the accompanying drawings, in which Figure l is a perspective view of part of a buggy-seat provided with my improvements. Fig. 2 is a central vertical section of one form of my coupling device drawn to about full size. Fig. 3 is a perspective view of my seatiron detached. Fig. i is a view similar to Fig. 2 of another form of my coupling. Fig. 5 is a detail view, in section, of the coupling and part of the seat-iron and back-support, showing how the parts are secured together. Fig. 6 is an elevation of the coupling-piece.

In the different view like parts are indicated by similar reference-letters.

The seat-irons are made in two parts, A and The part Abends over the upper edge of the seat in the usual way, but does not extend down to the bottom. The shank is made hol low to receive the part B, which is adapted to slide within part A, so that whatever the depth of the back and sides of the seat may be the same irons may be extended or shortened to fit it. The sliding connection between the two pieces may be made dovetailed or T- shaped in cross-section instead of the form shown, so'that the parts may slide without lateral motion. I

The coupling 0 is preferably made of cast malleable metal. It has a transverse perforation to receive the rail D and a vertical perforation to receive the lower ends of the backsupporting bars E F F. The upper portion of the screw-threaded ends of the back braces the parts are firmly clamped together, as seen in Fig. 5.

In Fig. 2 I have shown the vertical bore cone-shaped to near the lower end, which is screw-threaded to receive the thread upon the shank of the backsupporting pieces E, which, when this form is used, should be tightened down upon the rail D before the upper ends are secured to the back H.

The forward seat-irons have perforated projections a, extending outwardly to receive the upper end of the handle I, which is passed through it and secured in any suitable manner.

\Vhen the rail D is made in two parts to be united at the back, the pieces 0, which are to receive the braces F and F, are slipped over the rail D before the back-corners are bent, and when the rail is made in one piece all of the couplings O are slipped on before the rail is bent, and the pieces for the seat-irons and top are completed.

It is evident that the coupling 0 and the seat-iron A may be cast in one piece 5 but the form shown is preferable, as thus they are adapted for use with any seat-iron, and may be sold separate from the other parts shown.

I claim as new and desire tosecure by Letters Patent 1. A coupling for shifting-rails, consisting of a pillar resting upon the seat-iron and having a perforated boss at its upper end to re a vertical perforation communicating with the transverse perforation in the boss, in combination with the bolt or back brace having a diminished part to pass through the said pillar and seat-iron when the shifting-rail is in place, and an enlarged upper portion to bear upon and firmly hold the rail in place when the nut G is tightened, substantially as specified.

2. The combination, substantially as specified, of a buggy shifting-rail with coupling 0, rods E, nuts G, and the buggy seat-irons.

3. In combination with a shifting-rail for 'buggies the adjustable seat-iron composed of pieces A and B, said pieces being adapted to slide one within the other, for the purpose specified.
